Lateral Hind-Foot Endoscopic Anterolateral/Posterolateral (LEAP) Subtalar Arthrodesis: An Effective Minimally Invasive Technique to Achieve Subtalar Fusion and Deformity Correction.

ABSTRACT: Arthrodesis surgery aims to provide relief for chronic joint pain and correct limb alignment by achieving a stable union between articulating bones. The key factors to achieving sound arthrodesis is adequate debridement of arthritic cartilage and creating well-apposed bleeding subchondral bone surfaces without compromising the surrounding soft tissue envelope. Arthroscopic subtalar arthrodesis is technically demanding but provides better visualization of the articular surfaces and is safer for the surrounding soft tissues compared to the open approach. Early published reports of the arthroscopic subtalar arthrodesis from the lateral sinus tarsi approach and posterior approach have shown promising results with high rates of union and less wound healing complications. However, there are concerns about access to all facets of subtalar joint, nerve injury, and deformity correction. In this technique, the article authors describe the lateral endoscopic anterolateral/posterolateral (LEAP) approach for subtalar arthrodesis to improve visualization and access to all facets of the subtalar joint to ensure adequate preparation of apposing surfaces, sound union, and facilitate deformity correction of hind-foot. Strategic portal placement also avoids injury to sural nerve. This is a safe and effective minimally invasive technique for subtalar arthrodesis.

Anterolateral Arthroscopic Posterior Subtalar Arthrodesis: The Surgical Technique.

Project description:The effectiveness of subtalar arthrodesis has been well documented in treating degenerative subtalar joint disease. The arthroscopic subtalar approach for arthrodesis has also been proved to give excellent results in terms of bone fusion rates and reduction of wound-related pain and complications. To date, the main concerns about arthroscopy have regarded incision-related neurologic complications such as lesions of the tibial, fibular, and sural nerves. In this context, we present a 2-portal lateral (anterior and middle) approach to arthroscopic subtalar arthrodesis, recently documented in the literature, that provides similar excellent access to the joint with a lower risk of nerve damage.

Endoscopic Revision Subtalar Arthrodesis.

Project description:Varus malunion after subtalar arthrodesis is considered to be the worst deformity in hindfoot alignment. Poor clinical outcome is expected if there is more than 10° of varus malunion with lateral column overload. Open revision subtalar arthrodesis is associated with high rates of complications, especially involving soft tissue and nonunion. The purpose of this Technical Note is to describe the technical details of endoscopic revision subtalar arthrodesis in which the correction of varus malunion is performed with a minimally invasive technique, which may reduce the risk of soft tissue complications and nonunion.

Arthroscopic Posterior Subtalar Arthrodesis: Surgical Technique.

Project description:Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

Lateral Arthroscopic Subtalar Arthrodesis for Talocalcaneal Coalition: Surgical Technique.

Project description:Resection of symptomatic talocalcaneal coalitions (TCCs) has been performed for patients with normal tarsal joints and <50% involvement of the subtalar joint. For those with TCCs >50% of subtalar articulation or/and subtalar arthritis, a subtalar arthrodesis is done. The purpose of this Technical Note is to describe the arthroscopic resection of TCC and talocalcaneal arthrodesis during the same procedure by using a 2 lateral portal technique. With the patient in lateral decubitus under general or locoregional anaesthesia, the foot and ankle are extended beyond the edge of the surgical table. A lateral portal is created 1 cm anterior to the tip of the lateral malleolus in which the arthroscope is introduced. The anterolateral portal is created 1 cm inferior and 2 cm anterior to the tip of the lateral malleolus. The posterior subtalar surface is prepared progressively. The TCC resection is completed. The fixation is obtained with 2 cannulated screws. The arthroscopic resection of TCC and subtalar arthrodesis during the same procedure by using 2 lateral portals can be done for correctly selected patients.

Arthroscopic Lapidus Arthrodesis of the First Tarsometatarsal Joint for Treatment of Hallux Valgus Deformity of the Foot.

Project description:Hypermobility of the first tarsometatarsal joint can associate with different clinical problems, e.g., hallux valgus, hallux elevatus, hallux rigidus, and transverse metatarsalgia or arthritis of the second metarsocuneiform joint. The first tarsometatarsal joint may also contribute to other foot deformities involving the medial foot column. Osteoarthritis of this joint is one of the causes of medial foot pain. Arthrodesis of the first tarsometatarsal joint (modified Lapidus procedure) is indicated for these conditions, which are resistant to conservative treatment. Lapidus arthrodesis has several potential complications, including first metatarsal shortening, metatarsal elevates, and nonunion. Arthroscopic Lapdius arthrodesis has been reported to reduce these complications. In this Technical Note, the technical details of arthroscopic Lapidus arthrodesis is described.

Application of 3D-printed Customized Guides in Subtalar Joint Arthrodesis.

Project description:ObjectiveTo explore the feasibility of 3D printed customized guides assisting the precise drilling of Kirschner wires in subtalar joint arthrodesis.MethodsWe retrospectively reviewed the data of 29 patients (30 subtalar joints) who underwent subtalar joint arthrodesis between 1 July 2013 and 31 December 2017. The customized guides were designed on a full-scale 3D polylactic acid model made from computed tomography (CT) data of patients by Model Intestinal Microflora in Computer Simulation (MIMICS) software, which were manufactured by 3D printing technology. A total of 14 joints used customized guides (experimental group); the remained 16 joints used the traditional method (control group). The time of drilling the Kirschner wires to the correct position, the time of subtalar fusion, American Orthopaedic Foot & Ankle Society (AOFAS) scores, and complications were evaluated in both groups.ResultsAll customized guides were successfully manufactured. In the experimental group, it took 2.1 ± 0.7 min to drill the Kirschner wire to the satisfactory position, and 2 cases needed to be re-drilled; in the control group, it took 4.6 ± 1.9 min to drill the Kirschner wire to the satisfactory position (P < 0.05), and 8 cases needed to be re-drilled. No serious complications occurred in both groups during and after the surgery. Postoperative radiographic fusion was confirmed in all cases. No significant difference was observed in the fusion time and AOFAS scores 1 year postoperatively between the two groups (P > 0.05).ConclusionIt is safe to apply 3D-printed customized guides for subtalar joint arthrodesis, which can assist the accurate drilling of Kirschner wires into the appropriate position according to the preoperative plan, and reduce the operation time as well as intraoperative radiation.

Anterior and Posterior Subtalar Arthroscopy Via Anterolateral and Dorsolateral Portals.

Project description:Sinus tarsi syndrome is the clinical syndrome of lateral heel pain with local tenderness at the sinus tarsi and is frequently associated with a history of inversion sprain to the ankle. The lateral heel pain can be due to the capsule-ligamentous structures lateral to the axis of the anterior and posterior subtalar joints. Anterior and posterior subtalar arthroscopies are needed to detect and treat the disorders of both joints. In this Technical Note, we describe the details of a 2-portal arthroscopic approach to both anterior and posterior subtalar joints. This allows complete examination of all the possible sources of lateral heel pain in sinus tarsi syndrome.

Triple Arthrodesis for Adult-Acquired Flatfoot Deformity.

Project description:Originally described as a means to address fixed deformities or uncontrolled movement of the hindfoot observed in paralytic foot deformities, triple arthrodesis has evolved into a powerful procedure for the correction of a variety of foot deformities. Over the past decade, multiple advances have been made with respect to diagnostic imaging, fixation options, bone graft substitutes, and postoperative regimens. While this operation requires experience and skill to execute, when properly performed, it allows for correction of deformity and a plantigrade and ideally pain-free foot for ambulation. The purpose of this review is to highlight advances in the procedure and its application to the rigid planovalgus foot.Level of evidenceLevel V, review.

Treatment of Malunited Calcaneal Fracture With Posttraumatic Subtalar Osteoarthritis Using Lateral Endoscopic Calcaneoplasty With Posterior Arthroscopic Subtalar Arthrodesis.

Project description:Malunion of calcaneal fractures is a common complication after improper nonoperative treatment. It may develop into posttraumatic subtalar osteoarthritis, lateral calcaneal wall prominence, and severe foot deformities. This Technical Note reports the technical aspects of lateral endoscopic calcaneoplasty with posterior arthroscopic subtalar arthrodesis for the treatment of malunited calcaneal fracture with lateral calcaneal wall prominence and posttraumatic subtalar osteoarthritis. This technique was chosen because it can reduce the risk of wound complication compared with a conventional lateral extensile approach. This Technical Note describes the use of the technique in a patient with prone position. This offers the advantages of easier access to the lateral surface of the calcaneus and posterior facet of the subtalar joint, and is less invasive to the soft tissue envelope on the lateral side of the foot. Moreover, the concomitant bone void area of the subtalar joint can be dealt with by an arthroscopic procedure.
